* Upgrade closure and include hints on how to include the closure library in the build.
* Revert build-uncomprssed.
* Sort uncompressed.
* nit: comment.
* Google changed from an Inc to an LLC.
This happened back in 2017 but we didn’t notice. Officially we should update files from Inc to LLC when they are changed as part of regular edits, but this is a nightmare to remember for the next decade.
* Remove project description/titles from licenses
This is no longer part of Google’s header requirements. Our existing descriptions were useless (“Visual Blocks Editor”) or grossly obselete (“Visual Blocks Language”).
* License no longer requires URL.
* Fix license regexps.
No Blockly instances need both Horizontal and Vertical flyouts. Dropping one of these saves 2 KB. Some don’t need flyouts at all (e.g. Blockly Games Puzzle or readonly documentation blocks).
This drops the compiled size by 25 kb if there are no categories. Which also indicates that the toolbox itself suffers from really bad bloat. The toolbox should not represent 1/6th of our codebase.
* Move fields and renderers into their own entry point so folks are able to be more selective about which fields and renderers they include in their bundle.
